5 hour rule?

[canadianpizza]

the 5 hour rule is to let ur wang "cool down" so that the PE exercises aren't nullified right

why 5 hours? why not 2 hours or 10 hours?

is 5 hour just a ball park safety time to rest or is there some scientific proof that said that 5 hours is the perfect time to wait?

The 5 hour rule is just a theory that some stick to and some dont. It is generally agreed that you shouldnt wank a little before and a little after PE'ing but 5 hours was just a ball park figure.
